Acid Reflux Medications
Proton pump inhibitors and H2 blockers for GERD, ulcers, and acid reflux.
GERD Meds
Guide to Acid Reflux & Ulcer Treatment
Acid reflux and peptic ulcer disease arise when gastric acid breaches the protective lining of the esophagus or stomach, causing discomfort, inflammation, and potential tissue damage. The primary therapeutic aim is to suppress acid production, promote mucosal healing, and alleviate symptoms such as heartburn, regurgitation, and epigastric pain. Clinicians prescribe medications that either block the final step of acid secretion-proton pump inhibitors (PPIs)-or inhibit histamine-2 receptors on parietal cells, the H2 receptor antagonists (H2 blockers). These agents are indicated for gastro-oesophageal reflux disease (GERD), erosive oesophagitis, duodenal and gastric ulcers, and for prevention of ulcer recurrence in patients on non-steroidal anti-inflammatory drugs (NSAIDs). Treatment is typically tailored to disease severity, patient comorbidities, and response to initial therapy. Common therapeutic classes within this category include PPIs, H2 blockers, and adjunctive agents such as antacids and cytoprotective compounds that reinforce the gastric mucosal barrier.
Understanding Acid Reflux & Ulcer Treatment
Acid reflux and ulcer treatment encompasses medications that directly reduce gastric acidity or protect the mucosal surface. The condition spectrum includes uncomplicated GERD, severe erosive oesophagitis, and both duodenal and gastric ulcerations. Proton pump inhibitors, such as omeprazole and esomeprazole, block the H⁺/K⁺-ATPase enzyme, the final step in acid secretion, providing prolonged and potent acid suppression. H2 blockers, including ranitidine and famotidine, competitively inhibit histamine binding at H2 receptors, yielding a faster but shorter-acting reduction in acid output. Regulatory bodies in Singapore classify PPIs and H2 blockers as prescription-only medicines, while over-the-counter antacids are available for mild symptom relief. The category also spans adjuncts like sucralfate, which form a protective coating over ulcerated tissue, and alginate-based formulations that create a raft to limit reflux. Therapeutic goals focus on symptom control, mucosal healing, and prevention of complications such as Barrett’s oesophagus or bleeding ulcers.
Common Medications in This Category
Major Therapeutic Subcategories
- Proton Pump Inhibitors (PPIs): These agents inhibit the gastric H⁺/K⁺-ATPase pump, achieving up to 90 % reduction in basal acid secretion. They are first-line for erosive oesophagitis, chronic GERD, and ulcer healing, often administered once daily before breakfast.
- Histamine-2 Receptor Antagonists (H2 Blockers): By blocking H2 receptors on parietal cells, these drugs lower acid output, particularly during nocturnal periods. They are useful for mild to moderate GERD, nocturnal acid breakthrough, and as step-down therapy after initial PPI control.
- Antacids: Neutralize existing gastric acid through rapid chemical reactions, offering prompt relief of heartburn. They are appropriate for intermittent symptom management but do not promote mucosal healing.
- Cytoprotective Agents: Sucralfate adheres to ulcer bases, providing a physical barrier against acid and pepsin, while misoprostol enhances mucus production and bicarbonate secretion, reducing NSAID-induced ulcer risk.
- Alginate-based Formulations: Form a viscous gel that floats on gastric contents, limiting reflux of acid into the oesophagus. They are often combined with antacids for added symptom control.
Buying Acid Reflux & Ulcer Treatment Medications from Our Online Pharmacy
Why Choose Our Service
Access to acid-suppressing medication can be challenging when local pharmacies experience stock shortages or when travel to a clinic is inconvenient.

We partner with licensed international pharmacies that operate under stringent regulatory oversight, guaranteeing that each product meets the standards set by Singapore’s Health Sciences Authority. All medications are sourced from manufacturers adhering to Good Manufacturing Practice (GMP) guidelines, and every batch undergoes independent verification before dispatch.
Pricing & Access
Competitive pricing across the Acid Reflux & Ulcer Treatment portfolio lowers the financial barrier for long-term therapy. Generic formulations of omeprazole, pantoprazole, and ranitidine are offered at up to 45 % less than brand-name equivalents. Customers receive a Lifetime 10 % discount on all reorders, encouraging adherence to maintenance regimens without cost-related interruptions.
Discreet Delivery
Orders are packaged in unmarked, protective envelopes to safeguard privacy. Express shipping delivers within approximately seven days, while standard delivery arrives within three weeks. Both options include temperature-controlled handling to preserve medication integrity during transit.
Treatment Considerations & Safety
Medical supervision is essential when initiating acid-reducing therapy. PPIs require assessment of renal and hepatic function, and prolonged use may be associated with nutrient malabsorption, increased infection risk, and rare bone density concerns. H2 blockers are generally well tolerated but can interact with drugs that rely on gastric pH for absorption, such as certain antifungals and antiretrovirals. Antacids containing aluminum or magnesium may cause electrolyte imbalance if overused. Cytoprotective agents like misoprostol are contraindicated in pregnancy due to uterine contractile effects. Typical treatment duration for ulcer healing ranges from four to eight weeks, whereas chronic GERD often necessitates maintenance dosing with periodic reassessment. Regular monitoring-through symptom questionnaires, endoscopic evaluation, or laboratory tests-helps optimise therapy and mitigate adverse outcomes.
Frequently Asked Questions
-
What determines whether a PPI or an H2 blocker is prescribed? PPIs provide stronger, longer-lasting acid suppression and are preferred for erosive disease or ulcer healing, while H2 blockers are suitable for milder or intermittent symptoms and may be used as step-down therapy.
-
Can I switch between different PPIs without a doctor's approval? Switching can be done safely, but dosage equivalence varies among agents; a healthcare professional should confirm the appropriate conversion to maintain therapeutic efficacy.
-
How quickly do antacids relieve heartburn compared with PPIs? Antacids act within minutes by neutralising existing acid, whereas PPIs may take several days to achieve maximal acid control because they inhibit new acid production.
-
Are there any long-term risks associated with daily PPI use? Prolonged use has been linked to reduced calcium absorption, vitamin B12 deficiency, and a modest increase in gastrointestinal infections; periodic evaluation helps balance benefits and risks.
-
Do H2 blockers cause tolerance over time? Tolerance can develop after a few weeks of continuous use, diminishing their effectiveness; intermittent dosing or rotating to a PPI may mitigate this effect.
-
Can I take my ulcer medication with food? Most PPIs are best absorbed on an empty stomach, typically 30-60 minutes before a meal, while H2 blockers can be taken with or without food depending on the specific product instructions.
-
Will alginate-based treatments interfere with other reflux medications? Alginate formulations act locally and generally do not affect the systemic absorption of PPIs or H2 blockers, making them safe to combine for added symptom relief.
-
What lifestyle changes support medication effectiveness? Avoiding large meals, limiting caffeine and alcohol, elevating the head of the bed, and quitting smoking reduce reflux episodes, complementing pharmacologic therapy.
-
Is it safe to use over-the-counter antacids while on a prescription PPI? Short-term use for breakthrough symptoms is acceptable, but frequent reliance may indicate insufficient acid control and warrants medical review.
-
How are NSA-induced ulcers prevented? Co-prescribing a PPI or a cytoprotective agent with regular NSAID use lowers ulcer risk by maintaining gastric pH and protecting the mucosal lining.
-
Can acid-reducing meds affect the absorption of other prescriptions? Elevated gastric pH can decrease the bioavailability of drugs that require an acidic environment, such as certain antifungal and antiviral agents; dose adjustments may be necessary under professional guidance.
